Detection of address errors in memory devices using multi-segment error detection codes

Abstract:

A system including a user interface, a memory, and a processor configured to perform operations including receiving memory scrambling information including address scrambling information and data scrambling information, and associating one or more address bus bits of a plurality of address bus bits with an address grouping of a plurality of address groupings based on the address scrambling information is disclosed. In an embodiment, the address grouping corresponds to at least one address segment of a plurality of address segments. The operations include determining an error correction code for the at least one address segment that includes one or more address check bits. The operations include generating a physical layout of memory components based on the memory scrambling information. The memory components include at least one of the plurality of address bus bits, and the one or more address check bits.
